9 PLC Setup Power OFF Interrupt DisabledThis parameter determines whether the power OFF interrupt task is enabled.Parameter Settings Default FunctionPower Off InterruptdisabledON: DisabledOFF: EnabledONWhen this setting is set to OFF (enabled), thepower OFF interrupt task will be executedwhen power is interrupted.Relatedflags andwords---Note This parameter is not supported when the CJ1W-PD022 Power Supply Unit is mounted. Power OFF Interrupt TaskThis parameter determines whether a power OFF interrupt task will be executed when a power interruptionis detected. (When this parameter is set to ON, the regular program will just stop when apower interruption is detected.)The power OFF interrupt task will be stopped when the power hold time (processing time afterpower interrupt + power OFF detection delay time) has elapsed. The maximum power hold time is10 ms.When a power OFF detection delay time has to be set, be sure that the power OFF interrupt taskcan be executed in the available time (10 ms minus the power OFF detection delay time).Note This parameter is not supported when the CJ1W-PD022 Power Supply Unit is mounted. (Refer to A-5 Operationfor Power Interruptions.) Enable High-speed Interrupt Function (CJ2H CPU Units Only)This parameter is used to enable or disable high-speed interrupt function.Parameter Settings Default FunctionEnable highspeedinterruptfunctionOFF: Disable highspeedinterrupt function.ON: Enable high-speedinterrupt function.OFF (Disable highspeedinterrupts.)High-speed interrupt functionis enabled when the Enablehigh-speed interrupt functionOption is selected.Relatedflags andwords---High-speed interrupt function improve execution of interrupt tasks under certain restrictions. Fordetails, refer to 10-2-6 High-speed Interrupt Function.If the Use Synchronous Operation Check Box is selected in the PLC Setup, the Enable high-speedinterrupt function Check Box will be selected automatically. Synchronous Unit Operation Settings (CJ2H CPU Units Only)These settings are required to use the synchronous unit operation function.
